Description

本発明は、微粉体を大型容器から小型トナー容器に充填する装置に関し、具体的にはトナー、薬品、化粧品、食品等の粉体を粉体容器内に充填するための粉体充填装置が挙げられる。   The present invention relates to an apparatus for filling fine powder into a small toner container from a large container, and specifically, a powder filling apparatus for filling powder, such as toner, chemicals, cosmetics, and foods, into a powder container. It is done.

従来から、静電潜像現像用の粉体トナー(以下、単にトナーともいう。)を大型容器から小分けして他の容器に充填することが、行われてきた。例えば、特開平9−193902号公報(特許文献1)には、内部にトナー撹拌用オーガーを具備し底部にロータリーバルブを具備したトナー供給用容器からトナー受け容器にトナー粉体を充填する方法が開示されている。特許文献1には、該装置が、トナーに気体を導入することによるトナーの流動性を高める工程、該トナーを搬送配管を用いてトナー受け容器に搬送し、高密度化充填する工程を有することや、トナー中の気体分を分離し、分離気体中に随伴されるトナーを該気体と共にトナー供給用容器に再度返送することも開示されている。   Conventionally, powder toner for electrostatic latent image development (hereinafter, also simply referred to as toner) is subdivided from a large container and filled into another container. For example, Japanese Patent Laid-Open No. 9-193902 (Patent Document 1) discloses a method of filling a toner receiving container with toner powder from a toner supply container having a toner auger inside and a rotary valve at the bottom. It is disclosed. In Patent Document 1, the apparatus includes a step of increasing the fluidity of the toner by introducing a gas into the toner, and a step of transporting the toner to a toner receiving container using a transport pipe and filling the toner with a high density. In addition, it is also disclosed that the gas component in the toner is separated and the toner accompanying the separated gas is returned to the toner supply container together with the gas.

一方、静電潜像現像用トナーは、極く小粒径の粉体であって、流動性が悪く、凝集性が高いという問題を有し、特に最近では、現像された画像の解像力上昇の要求に答えるためますます小粒径化が進んでいるため、これらの問題はますます増大している。また、省エネルギー化及び瞬時高速定着の要求もあり、低温溶融性の樹脂が採用されることもあって、凝集性及び他物体表面への付着性やフィルミング性が問題となっている。   On the other hand, toner for developing an electrostatic latent image is a powder having a very small particle diameter, and has a problem of poor fluidity and high cohesiveness. Recently, the resolution of developed images has increased. These problems are aggravated as the particle size is increasingly reduced in response to demands. In addition, there is a demand for energy saving and instantaneous high-speed fixing, and a low-melting resin is sometimes used, which causes problems of cohesion, adhesion to other object surfaces, and filming.

これらの問題を解決可能な装置として、例えば特開2003−221003号公報(特許文献2)に開示されているトナー充填装置がある。該装置は、図11に示すように、大型容器内の微粉体トナーを計量槽に移送した後に該計量槽から小型トナー容器に充填するトナー充填装置であり、該計量槽がトナーの吐出開口部に所定量のみを小型トナー容器に充填するための充填量規制手段を有する装置である。特許文献2記載の装置においては、計量槽が第1のトナー流動化手段を有し、該大型容器と計量槽とが連結管により連通しており、該連結管には、大型容器から排出されるトナーを流動化して計量槽に導入する第2のトナー流動化手段が設けられている。   As an apparatus capable of solving these problems, for example, there is a toner filling apparatus disclosed in Japanese Patent Laid-Open No. 2003-221003 (Patent Document 2). As shown in FIG. 11, the apparatus is a toner filling apparatus that fills a small toner container from the measuring tank after the fine powder toner in the large container is transferred to the measuring tank, and the measuring tank has a toner discharge opening. And a filling amount regulating means for filling only a predetermined amount into a small toner container. In the apparatus described in Patent Document 2, the measuring tank has a first toner fluidizing means, and the large container and the measuring tank communicate with each other through a connecting pipe, and the connecting pipe is discharged from the large container. Second toner fluidizing means is provided for fluidizing and introducing the toner to the metering tank.

上記計量槽における充填量規制手段は、吐出開口部を有する弾性体リングと、トナーの吐出を制御する吐出制御手段とからなり、該吐出制御手段は、計量槽内を昇降する吐出制御杆に装着された吐出量制御部材を昇降させて、該吐出量制御部材と吐出開口部を有する弾性体リングとの開閉度を制御するというものである。   The filling amount regulating means in the measuring tank comprises an elastic ring having a discharge opening and a discharge control means for controlling toner discharge, and the discharge control means is mounted on a discharge control rod that moves up and down in the measuring tank. The discharged amount control member is moved up and down to control the degree of opening and closing of the discharged amount control member and the elastic ring having the discharge opening.

特許文献2記載のトナー充填装置の構成によれば、トナーの諸物性並びに配合性を損なうことなく、大型容器内に貯蔵されているトナーを流動化させ、小型容器に迅速かつ正確に分取することができる。
しかしながら、特許文献2記載の装置は、未だ満足できるものではなかった。即ち、特許文献2記載の装置を長時間使用すると、トナーの凝集体やゴミが計量槽に混入し、凝集体やゴミが吐出量制御部材と吐出開口部を有する弾性体リングとの間に溜まるという現象が発生した。その結果、吐出量制御部材の昇降を自在に行なうことができなくなり、甚だしい場合には、トナーの吐出量を制御することができなくなるという問題が発生していた。
According to the configuration of the toner filling device described in Patent Document 2, the toner stored in the large container is fluidized without losing various physical properties and compounding properties of the toner, and quickly and accurately sorted into the small container. be able to.
However, the apparatus described in Patent Document 2 has not yet been satisfactory. That is, when the apparatus described in Patent Document 2 is used for a long time, toner aggregates and dust are mixed into the measuring tank, and the aggregates and dust are collected between the discharge amount control member and the elastic ring having the discharge opening. The phenomenon that occurred. As a result, the discharge amount control member cannot be raised and lowered freely, and in a severe case, there has been a problem that the toner discharge amount cannot be controlled.

[3] The fine powder filling apparatus according to [1] or [2], wherein the fine powder is a powder toner for developing an electrostatic latent image.

本発明の微粉体充填装置によれば、大型容器内の微粉体トナーを計量槽に移送した後に該計量槽から小型トナー容器に充填するトナー充填装置において、充填制御に悪影響を及ぼす微粉体内の粉体凝集物やゴミの吐出量制御部への混入を防止することにより、長時間にわたって安定した稼動が確保される。   According to the fine powder filling device of the present invention, in the toner filling device for filling the small toner container from the measuring tank after the fine powder toner in the large container is transferred to the measuring tank, the powder in the fine powder adversely affecting the filling control. By preventing the agglomerates and dust from being mixed into the discharge amount control unit, stable operation can be ensured for a long time.

本発明の微粉体充填装置は、図1に示すように、大型容器(10)内の微粉体を計量槽(30)に移送した後に計量槽(30)から小型トナー容器(40)に充填する微粉体充填装置である。本発明においては、該大型容器(10)内の微粉体を計量槽(30)に移送する途中に網目状のフィルタ(1)が設けられている。かかるフィルタ(1)を設けることにより、微粉体内の凝集体やゴミが計量槽(30)に混入することを容易に防ぐことができる。従って、充填装置を長時間稼動させても、吐出量制御部材の昇降が不自由になることがなく、微粉体の吐出量を安定して制御することができる。   As shown in FIG. 1, the fine powder filling apparatus of the present invention transfers fine powder in a large container (10) to a measuring tank (30) and then fills the small toner container (40) from the measuring tank (30). It is a fine powder filling device. In the present invention, a mesh-like filter (1) is provided in the middle of transferring the fine powder in the large container (10) to the measuring tank (30). By providing such a filter (1), it is possible to easily prevent agglomerates and dust in the fine powder from entering the measuring tank (30). Therefore, even if the filling device is operated for a long time, the discharge amount control member is not raised and lowered, and the discharge amount of the fine powder can be controlled stably.

本発明で用いる網目状のフィルタの目開きは、0.05〜3.00mmであることが好ましく、0.50〜2.50mmであることがより好ましく、1.00〜2.00mmであることが更に好ましい。フィルタの目開きが0.05mm未満の場合は、微粉体の凝集体やゴミの混入を防ぐことはできるが、微粉体の通過までも制限されて生産性が低下する虞がある。一方、3.00mmを超える場合は、微粉体の凝集体やゴミの混入を防ぐことができない虞がある。   The mesh size of the mesh filter used in the present invention is preferably 0.05 to 3.00 mm, more preferably 0.50 to 2.50 mm, and 1.00 to 2.00 mm. Is more preferable. When the aperture of the filter is less than 0.05 mm, it is possible to prevent the agglomeration of fine powder and dust from being mixed in, but there is a possibility that productivity is reduced because the passage of the fine powder is limited. On the other hand, when it exceeds 3.00 mm, there is a possibility that it is not possible to prevent agglomeration of fine powders and contamination of dust.

該網目状のフィルタは、微粉体の凝集を防ぐために、導電性の材質からなることが好ましい。網目状のフィルタの導電性が低いと微粉体が凝集しやすく、特に微粉体がトナーの場合、凝集しやすい傾向が大きい。導電性の材質に制限はないが、例えば、ステンレスが好ましく挙げられる。その他にも、抵抗値が10Ωの導電性の樹脂が挙げられる。 The mesh filter is preferably made of a conductive material in order to prevent aggregation of fine powder. When the conductivity of the mesh-like filter is low, the fine powder tends to aggregate. In particular, when the fine powder is toner, the tendency to easily aggregate is large. Although there is no restriction | limiting in an electroconductive material, For example, stainless steel is mentioned preferably. In addition, a conductive resin having a resistance value of 10 7 Ω can be given.

本発明においては、図2に示すように、大型容器(10)と計量槽(30)とが、大型容器(10)の微粉体排出口(11)と計量槽(30)の微粉体導入口(69)との間を結ぶ連結管(20)により連通しており、連結管(20)の途中に網目状のフィルタ(1)が設けられていることが好ましい。具体的には、図3に示すように、連結管(20)をその途中で分離できるようにフランジ(2a)(2b)を設け、フランジ(2a)とフランジ(2b)の間に、網目状のフィルタ(1)をパッキン(3a)(3b)で挟んで挿入し、フランジ(2a)とフランジ(2b)をねじ止めすることが好ましい。このようにフィルタ(1)が設けられていると、簡単に装着でき、交換/確認が容易である。また、作業環境及び作業者を汚すことがない。   In the present invention, as shown in FIG. 2, the large container (10) and the measuring tank (30) are composed of a fine powder outlet (11) of the large container (10) and a fine powder inlet of the measuring tank (30). It is preferable that the connecting pipe (20) communicates with the connecting pipe (69), and a mesh-like filter (1) is provided in the middle of the connecting pipe (20). Specifically, as shown in FIG. 3, flanges (2a) and (2b) are provided so that the connecting pipe (20) can be separated in the middle, and a mesh-like shape is provided between the flange (2a) and the flange (2b). It is preferable to insert the filter (1) between the packings (3a) and (3b) and screw the flange (2a) and the flange (2b) with screws. When the filter (1) is provided in this way, it can be easily mounted and can be easily replaced / confirmed. Moreover, it does not pollute the work environment and workers.

本発明におけるフィルタを設ける場所は、上記態様に限定されない。例えば、大型容器と計量槽とを、大型容器の微粉体排出口と該計量槽の微粉体導入口の間の連結管により連通し、微粉体導入口に網目状のフィルタを設けてもよい(図示はしない。)。   The place where the filter according to the present invention is provided is not limited to the above embodiment. For example, the large container and the measuring tank may be communicated with each other by a connecting pipe between the fine powder discharge port of the large container and the fine powder introducing port of the measuring tank, and a mesh-like filter may be provided at the fine powder introducing port ( Not shown).

次に、本発明の微粉体充填装置のフィルタ以外の各部分の好ましい構成について、具体的に説明する。但し、本発明は以下の説明によって限定されるものではない。
図1は、本発明の充填装置の一例を示す説明図である。図1の充填装置例において、大型容器(10)内の微粉体トナーは、計量槽(30)を介して小型トナー容器(40)に充填される。大型容器(10)と計量槽(30)とは、大型容器(10)の微粉体排出口(11)と計量槽(30)の微粉体導入口(69)を結ぶ連結管(20)により連通している。さらに、計量槽(30)は、充填される微粉体吐出用の吐出開口部(31)に、この吐出開口部(31)を開閉して前記小型微粉体容器(40)に所定量のみ充填するための充填量規制手段(32)を有することが好ましい。
Next, the preferable structure of each part other than the filter of the fine powder filling apparatus of the present invention will be specifically described. However, the present invention is not limited by the following description.
FIG. 1 is an explanatory view showing an example of the filling apparatus of the present invention. In the example of the filling apparatus in FIG. 1, the fine powder toner in the large container (10) is filled into the small toner container (40) via the measuring tank (30). The large container (10) and the measuring tank (30) communicate with each other by a connecting pipe (20) connecting the fine powder discharge port (11) of the large container (10) and the fine powder introduction port (69) of the measuring tank (30). doing. Furthermore, the measuring tank (30) opens and closes the discharge opening (31) for discharging the fine powder to be filled, and fills the small fine powder container (40) by a predetermined amount. It is preferable to have a filling amount regulating means (32) for this purpose.

大型容器(10)は、内部に収納された微粉体の滑落を妨げない程度に傾斜した内壁部分(12)を有することが好ましく、この傾斜した内壁部分(12)により、内部に収納された微粉体の微粉体排出口(11)までの排出が円滑化される。この例の装置においては、傾斜した内壁部分(12)が、前記大型容器(10)下部のホッパ状の構造部分(13)の一部になっていることが好ましい。   The large container (10) preferably has an inner wall portion (12) that is slanted to such an extent that it does not prevent the fine powder housed therein from sliding off. The slanted inner wall portion (12) allows fine powder housed inside. The discharge to the fine powder discharge port (11) of the body is facilitated. In the apparatus of this example, the inclined inner wall portion (12) is preferably a part of the hopper-like structural portion (13) below the large container (10).

計量槽(30)に設けられた第1の微粉体流動化手段(33)の場合、連結管(20)に設けられた第2の微粉体流動化手段(21)の場合も同様であるが、、このような微粉体流動化手段によって、微粉体流出の中断、或いは逆にボタ落ち、を防止することができ、かつ、このような微粉体流動化手段への送気量を加減することにより、微粉体流出量を調節することができ、送気された気体との混合により形成される微粉体雲(微粉体と気体との混合により形成される雲状の微粉体浮遊物)の大きさを調節することができる。   In the case of the first fine powder fluidization means (33) provided in the measuring tank (30), the same applies to the case of the second fine powder fluidization means (21) provided in the connecting pipe (20). By such a fine powder fluidizing means, it is possible to prevent interruption of fine powder outflow or, conversely, dropping of the button, and to increase or decrease the amount of air supplied to such fine powder fluidizing means. The amount of fine powder outflow can be adjusted by this, and the size of the fine powder cloud (cloud-like fine powder suspended matter formed by mixing fine powder and gas) formed by mixing with the sent gas Can be adjusted.

大型容器(10)と計量槽(30)とは、連結管(20)の上部に設けられた上部連通管(50)によっても連結されており、この上部連通管(50)は計量槽(30)から大型容器(10)に向かって上方向に傾斜していることが好ましい。この上部連通管(50)は、計量槽(30)内の圧力を大型容器(10)内の圧力に等しく保つ役割を有する他、第1の微粉体流動化手段(33)からの噴出気体の量が多すぎる等の何らかの理由により計量槽(30)中に所望以上に大きな微粉体雲が形成された場合には、この上部連通管(50)により、過剰な気体を大型容器(10)に抜き去ることができ、上方向に傾斜していることにより、随伴する微粉体粒子を計量槽(30)に戻すことができる。   The large container (10) and the measurement tank (30) are also connected by an upper communication pipe (50) provided on the upper part of the connection pipe (20). The upper communication pipe (50) is connected to the measurement tank (30). ) To the large container (10). The upper communication pipe (50) has a role of keeping the pressure in the measuring tank (30) equal to the pressure in the large container (10), and is also used for the ejection gas from the first fine powder fluidizing means (33). When a cloud of fine powder larger than desired is formed in the measuring tank (30) for some reason such as an excessive amount, excess gas is transferred to the large container (10) by the upper communication pipe (50). By being able to be removed and inclined upward, the accompanying fine powder particles can be returned to the measuring tank (30).

大型容器(10)底部の微粉体排出口(11)から排出された微粉体粉体は、連結管(20)を通って計量槽(30)へ移動する。連結管(20)の少なくとも底面部分には、長さ方向のほぼ全面に亘って導入気体が吹き出す多孔質板のエアースライダ、即ち第2の微粉体流動化手段(21)が設けられており、この第2の微粉体流動化手段(21)から吹き込まれた気体で、連結管(20)から計量槽(30)へ移動される微粉体を流動化することが好ましい。連結管(20)は、計量槽(30)に向かって下方向に傾斜しており、流動化された微粉体の計量槽(30)への滑落がこれによっても補助される。   The fine powder discharged from the fine powder discharge port (11) at the bottom of the large container (10) moves to the measuring tank (30) through the connecting pipe (20). At least a bottom surface portion of the connecting pipe (20) is provided with an air slider of a porous plate from which the introduced gas blows out over almost the entire length direction, that is, a second fine powder fluidizing means (21). It is preferable to fluidize the fine powder moved from the connecting pipe (20) to the measuring tank (30) with the gas blown from the second fine powder fluidizing means (21). The connecting pipe (20) is inclined downward toward the measuring tank (30), and the sliding of the fluidized fine powder onto the measuring tank (30) is also assisted by this.

微粉体排出口(11)から排出された微粉体粉体は、連結管(20)を介して計量槽(30)に送られる。この例における計量槽(30)は、所望量のみの微粉体の的確、かつ円滑な充填のための充填量規制手段(32)を吐出開口部(31)に有していることが好ましい。該「所望量」は、適宜設定し直すことができる。   The fine powder discharged from the fine powder discharge port (11) is sent to the measuring tank (30) through the connecting pipe (20). The measuring tank (30) in this example preferably has a filling amount regulating means (32) for accurate and smooth filling of only a desired amount of fine powder in the discharge opening (31). The “desired amount” can be reset as appropriate.

この例の装置における充填量規制手段(32)は、吐出開口部(31)を有する弾性体リング(32a)と、吐出開口部(31)からの微粉体の吐出を制御する吐出制御手段(32b)とからなり、吐出制御手段(32b)は、計量槽(30)内を昇降する吐出制御杆(32c)に装着された吐出制御部材(32d)からなることが好ましい。吐出制御部材(32d)は、吐出開口部(31)と挿入−離脱して該吐出開口部(31)を開閉する円錐状の部材であり、吐出開口部(31)の開閉程度は、吐出制御杆(32c)の計量槽(30)内での昇降程度に依存する円錐状の吐出制御部材(32d)の弾性体リング(32a)の開口部(31)への挿入程度、嵌合程度によって調節されることが好ましい。   The filling amount regulating means (32) in the apparatus of this example includes an elastic ring (32a) having a discharge opening (31) and a discharge control means (32b) for controlling the discharge of fine powder from the discharge opening (31). The discharge control means (32b) preferably includes a discharge control member (32d) mounted on a discharge control rod (32c) that moves up and down in the measuring tank (30). The discharge control member (32d) is a conical member that opens and closes the discharge opening (31) by being inserted into and removed from the discharge opening (31), and the degree of opening and closing of the discharge opening (31) depends on the discharge control. Adjust depending on the degree of insertion and fitting of the conical discharge control member (32d) into the opening (31) of the elastic ring (32a), which depends on the degree of elevation of the basket (32c) in the measuring tank (30). It is preferred that

上記のように構成されている場合、吐出制御部材(32d)の小半径の円錐先端が開口部(31)より完全に抜け去るまで上昇したときが全開状態(充填される微粉体の自由吐出)であり、吐出制御部材(32d)の大半径の円錐根本端まで開口部(31)に完全に嵌合するように下降し挿入したときが閉状態(微粉体の吐出停止)であり、その途中の状態即ち吐出制御部材(32d)が該開口部(31)から完全に抜け切らずかつ完全に下降し切らない状態であって、吐出制御部材(32d)の中程度の大きさの円錐半径箇所と該開口部(31)との間に間隙が保持される程度に挿入されたときはその挿入レベルに応じた半開状態(微粉体の部分吐出)である。図中、符号(37)で示される柔軟性ある覆部材は、吐出開口部(31)の下のスリーブ(30a)に設けたものであるが、この覆部材(37)は、省略することも可能である。   When configured as described above, the fully-opened state (free discharge of fine powder to be filled) is when the small radius conical tip of the discharge control member (32d) is lifted up completely from the opening (31). And when it is lowered and inserted so as to be completely fitted into the opening (31) to the cone end of the large radius of the discharge control member (32d), it is in a closed state (stopping the discharge of fine powder). In other words, the discharge control member (32d) is not completely removed from the opening (31) and is not completely lowered, and the discharge control member (32d) has a medium conical radius portion. And the opening (31) are in a semi-open state (partial discharge of fine powder) according to the insertion level. In the figure, the flexible cover member indicated by reference numeral (37) is provided on the sleeve (30a) under the discharge opening (31), but this cover member (37) may be omitted. Is possible.

図1に示されるように、弾性体リング(32a)は、外周縁から内部の吐出開口部(31)に向かうにつれて肉厚が薄くなった断面くさび形をしていることが好ましく、この場合、吐出制御部材(32d)が完全挿入されたときに接触せざるを得ない内側の方が、柔軟性が大きい。このような構造の弾性体リング(32a)は、吐出制御部材(32d)と接触しても、弾性体リング(32a)や吐出制御部材(32d)表面に微粉体のフイルミングを生じない。弾性体リング(32a)が吐出制御部材(32d)と接触しても、両者の間に不可避的に残存するトナーにストレスをほとんど与えないためである。   As shown in FIG. 1, the elastic ring (32a) preferably has a wedge-shaped cross section with a thickness that decreases from the outer peripheral edge toward the internal discharge opening (31). The inner side where the discharge control member (32d) has to come into contact when it is completely inserted is more flexible. Even when the elastic ring (32a) having such a structure contacts the discharge control member (32d), filming of fine powder does not occur on the surface of the elastic ring (32a) or the discharge control member (32d). This is because even if the elastic ring (32a) comes into contact with the ejection control member (32d), the toner inevitably remaining between them is hardly stressed.

本発明においては、計量槽(30)の吐出開口部(31)の充填量規制手段は、この例示されたものに限らず、例えば吐出開口部(31)を弾性体材料で適宜の形状に形成し、開口度規制部材を、この吐出開口部に隣接して面方向に所定距離スライド又は進退する板状部材とすることができ、また、吐出開口部に合致した開口を有する部材の移動による両開口の相対的位置関係により開口程度を調節可能なものとすることができる。   In the present invention, the filling amount regulating means of the discharge opening (31) of the measuring tank (30) is not limited to this exemplified one, and for example, the discharge opening (31) is formed into an appropriate shape with an elastic material. In addition, the opening degree regulating member can be a plate-like member that slides or moves forward and backward in the surface direction adjacent to the discharge opening, and both of the members by moving the member having the opening that matches the discharge opening. The degree of opening can be adjusted by the relative positional relationship of the openings.

上記吐出制御杆(32c)の昇降は、駆動制御装置(39a)により制御される駆動源(39b)によって駆動される駆動装置(39)により行われることが好ましい。吐出制御杆(32c)の昇降のための駆動装置(39)は、エアー圧シリンダ、モータ、油圧シリンダ等の適宜手段により行うことができるが、この例の装置においては、エアー圧シリンダを用いている。これにより、第1の微粉体流動化手段(33)、第2の微粉体流動化手段(21)、第3の微粉体流動化手段(15)に用いられる空気のための圧縮空気用原配管から分岐させて駆動源として用いることができる。   The discharge control rod (32c) is preferably moved up and down by a drive device (39) driven by a drive source (39b) controlled by the drive control device (39a). The drive device (39) for raising and lowering the discharge control rod (32c) can be performed by appropriate means such as an air pressure cylinder, a motor, a hydraulic cylinder, etc. In this example device, an air pressure cylinder is used. Yes. Thereby, the original piping for compressed air for the air used for the first fine powder fluidization means (33), the second fine powder fluidization means (21), and the third fine powder fluidization means (15). And can be used as a drive source.

この例における第1の微粉体流動化手段(33)は、気体を噴出するための多数の微細孔を有し、各微細孔は内部で相互に連通している多孔体へ加圧気体を導入する第1の気体導入管(33a)を有することが好ましい。同様に、第2の微粉体流動化手段(21)は、気体を噴出するための多数の微細孔を有し、各微細孔は内部で相互に連通している多孔体へ加圧気体を導入する第2の気体導入管(21a)を有することが好ましく、第3の微粉体流動化手段(15)は、気体を噴出するための多数の微細孔を有し、各微細孔は内部で相互に連通している多孔体へ加圧気体を導入する第3の気体導入管(15a)を有することが好ましい。この例の装置においては、表面が平滑な多孔質燒結体を用いている。また図示してないが、流動化したトナーの粉塵爆発を防止するため、この例のトナー充填装置においては、発生した静電気を除電するための除電手段が設けられていることが好ましい。   The first fine powder fluidizing means (33) in this example has a large number of fine holes for ejecting gas, and each fine hole introduces pressurized gas into a porous body communicating with each other inside. It is preferable to have a first gas introduction pipe (33a). Similarly, the second fine powder fluidizing means (21) has a large number of fine holes for ejecting gas, and each fine hole introduces pressurized gas into a porous body communicating with each other inside. Preferably, the third fine powder fluidizing means (15) has a number of fine holes for ejecting gas, and each fine hole is mutually inside. It is preferable to have a third gas introduction pipe (15a) for introducing a pressurized gas into the porous body communicating with the gas. In the apparatus of this example, a porous sintered body having a smooth surface is used. Although not shown, in order to prevent dust explosion of the fluidized toner, it is preferable that the toner filling device of this example is provided with a static elimination means for neutralizing the generated static electricity.

図1に示されるように、この例の装置においては、第1の微粉体流動化手段(33)は、所要の高微粉体吐出能を得るため、計量槽(30)の吐出開口部(31)の近所に、円周の全周に亘って設けられていることが好ましく、この場合、一部のみに細い帯状の第3の微粉体流動化手段(15)が設けられている大型容器(10)の場合とは異なる。微粉体粉体の移動量は吹込み空気量に比例する範囲があり、供給気体量を調節して移動量をほぼ一定にすることができるが、各微粉体流動化手段(33)(21)(15)の面積の大小、したがって同様な気体噴出材料が用いられた場合には、孔部の多少は、供給可能気体量にも多いに関係する。特に吐出開口部(31)に向かって断面が狭くなる構造の計量槽(30)では、微粉体による架橋現象を防止するために、円周面に沿って気体の吹出口を数段階連続的に設けたり、螺旋方向へ気体が吹き出すような吹出し構造とすることができる。   As shown in FIG. 1, in the apparatus of this example, the first fine powder fluidizing means (33) has a discharge opening (31) of the measuring tank (30) in order to obtain a required high fine powder discharge ability. ) Is preferably provided over the entire circumference of the circumference, and in this case, a large container (in which only a small strip-shaped third fine powder fluidizing means (15) is provided in part) This is different from the case of 10). The amount of movement of the fine powder powder has a range proportional to the amount of blown air, and the amount of movement can be made almost constant by adjusting the amount of supplied gas. Each fine powder fluidizing means (33) (21) When the area of (15) is large and therefore the same gas ejection material is used, the number of holes is related to the amount of gas that can be supplied. In particular, in the measuring tank (30) having a structure in which the cross section becomes narrower toward the discharge opening (31), in order to prevent the cross-linking phenomenon due to the fine powder, the gas outlet is continuously provided in several steps along the circumferential surface. It can provide, or it can be set as the blowing structure which gas blows off to a spiral direction.

また、第1の気体導入管(33a)は、送気停止し、送気開始し、かつ送気量調節する第1送気調節弁(33b)を有し、同様に、第2の気体導入管(21a)は、送気停止し、送気開始することが好ましく、かつ送気量調節する第2送気調節弁(21b)を有し、第3の気体導入管(15a)は、送気停止し、送気開始することが好ましく、かつ送気量調節する第3送気調節弁(15b)を有することが好ましい。少なくとも、これら第1〜3の気体導入管(33a)(21a)(15a)のうちの少なくとも1つは、そのような送気調節弁を有することが望ましい。   The first gas introduction pipe (33a) has a first air supply control valve (33b) that stops air supply, starts air supply, and adjusts the air supply amount. Similarly, the second gas introduction pipe (33a) The pipe (21a) preferably stops air supply and starts air supply, and has a second air supply adjustment valve (21b) for adjusting the air supply amount, and the third gas introduction pipe (15a) It is preferable to stop the air and start the air supply, and it is preferable to have the third air supply adjustment valve (15b) for adjusting the air supply amount. At least one of the first to third gas introduction pipes (33a) (21a) (15a) preferably has such an air supply control valve.

一方、本発明の微粉体充填装置は、小型微粉体容器(40)への充填粉体微粉体量を管理するための充填微粉体重量管理手段を有することが好ましく、この例の装置における充填微粉体重量管理手段(60)は、小型微粉体容器(40)をその上に載置して充填微粉体重量を測定するためのロードセル(61)を有する。ロードセル(61)は、これを昇降して計量槽(30)と小型微粉体容器(40)の間隔を適宜変更するためのリフター(61a)上に設けられている。また、ロードセル(61)には、測定された充填粉体微粉体重量を表示するためのモニタ手段(63)が設けられている。   On the other hand, it is preferable that the fine powder filling device of the present invention has a filled fine powder weight management means for managing the amount of fine powder filled in the small fine powder container (40). The body weight management means (60) has a load cell (61) for placing the small fine powder container (40) thereon and measuring the weight of the filled fine powder. The load cell (61) is provided on a lifter (61a) for raising and lowering the load cell (61) to appropriately change the distance between the weighing tank (30) and the small fine powder container (40). The load cell (61) is provided with monitor means (63) for displaying the measured weight of the filled powder fine powder.

このようなモニタ手段としては、重量や圧力を受け弾性変形する程度に応じて変化した電圧を検知するような受圧検知手段からの電圧信号に基いて、又は受圧力に応じて直接起電力を変化させる圧電素子等の圧力検知素子からの発生信号に基いて、測定重量を表示できる公知の表示手段を用いることができ、モニタ手段(63)に表示された重量を見て微粉体の充填量を確認ながら、充填を行ない又は終了することができる。   As such a monitoring means, an electromotive force is directly changed based on a voltage signal from a pressure receiving detection means that detects a voltage changed according to the degree of elastic deformation due to weight or pressure, or directly according to the pressure received. A known display means capable of displaying the measured weight can be used based on a signal generated from a pressure detecting element such as a piezoelectric element, and the amount of fine powder filled can be determined by viewing the weight displayed on the monitor means (63). While confirming, filling can be performed or terminated.

また、本発明において必要不可欠ではないが、この例の微粉体充填装置における充填微粉体重量管理手段(60)は、ロードセル(61)における前記小型微粉体容器(40)の例えば空重量と微粉体が充填された該小型微粉体容器(40)の総重量とから、充填済み微粉体重量を演算する演算処理装置(62)を有することが好ましい。   Further, although not indispensable in the present invention, the filled fine powder weight management means (60) in the fine powder filling apparatus of this example is, for example, the empty weight and fine powder of the small fine powder container (40) in the load cell (61). It is preferable to have an arithmetic processing device (62) for calculating the weight of the filled fine powder from the total weight of the small fine powder container (40) filled with the.

上記演算処理装置(62)は、入力手段(64)を有し、該入力手段(64)により、例えばモニタ手段(63)に表示された重量を見つつ、微粉体の充填予定重量の入力、及び、入力された充填予定重量の変更を行うことができる。また、演算処理装置(62)は、その演算結果に基いて、駆動装置(39)の駆動源(39b)ための駆動制御装置(39a)に通信回線(67)から駆動指令信号を送信し、駆動制御装置(39a)は、それに基いて吐出制御杆(32c)を昇降させる。演算処理装置(62)としては、簡単なアナログ式電圧比較器からマイコンチップのようなものを含む各種CPUまで種々のものを用いる(アナログ式電圧比較器の場合には、無論、所定電位差に応じた例えばパルス信号に変換するAD変換器を付属させる)ことができる。   The arithmetic processing unit (62) has an input means (64), and the input means (64) is used to input the expected filling weight of fine powder while watching the weight displayed on the monitor means (63), for example. And the input filling weight can be changed. The arithmetic processing device (62) transmits a drive command signal from the communication line (67) to the drive control device (39a) for the drive source (39b) of the drive device (39) based on the calculation result, The drive control device (39a) raises and lowers the discharge control rod (32c) based on it. As the arithmetic processing unit (62), various devices are used from a simple analog voltage comparator to various CPUs including a microcomputer chip (in the case of an analog voltage comparator, of course, depending on a predetermined potential difference). For example, an AD converter for converting to a pulse signal can be attached).

前に説明したように、吐出制御杆(32c)を昇降させ、吐出制御部材(32d)の小半径の円錐先端が開口部(31)より完全に抜け去るまで上昇したときには全開状態であり、吐出制御部材(32d)の大半径の円錐根本端まで開口部(31)に完全に嵌合するように下降し挿入したときには全閉状態であり、その途中の状態即ち吐出制御部材(32d)が該開口部(31)から完全に抜け切らずかつ完全に下降し切らない状態であって、吐出制御部材(32d)の中程度の大きさの円錐半径箇所と該開口部(31)との間に間隙が保持される程度に挿入されたときはその挿入レベルに応じた半開状態であり、したがって何段階のレベルにも調節できるが、図1に示される微粉体の充填装置例においては、第1〜3の各気体導入管(33a)(21a)(15a)への送気量調節によっても充填を調節することができるので、吐出制御杆(32c)の昇降程度は、全閉状態と、全開状態と、それらの中間の半開状態としている。   As explained before, when the discharge control rod (32c) is moved up and down and the tip of the small radius cone of the discharge control member (32d) is lifted up completely from the opening (31), the discharge control rod (32c) is fully open. When the control member (32d) is lowered and inserted into the opening (31) to the end of the large radius cone, it is in a fully closed state, that is, the discharge control member (32d) is in the middle. Between the opening (31) and the medium-sized conical radius portion of the discharge control member (32d) that is not completely removed from the opening (31) and is not completely lowered and lowered. When it is inserted to such an extent that the gap is maintained, it is in a half-open state according to the insertion level, and can therefore be adjusted to any number of levels. In the example of the fine powder filling device shown in FIG. ~ 3 gas introduction pipes (33 ) (21a) Since the filling can be adjusted also by adjusting the amount of air supplied to (15a), the elevation of the discharge control rod (32c) is in the fully closed state, the fully open state, and the half open state between them. It is said.

この例における入力手段(64)は、コード発生器(バイナリーコード)としてのデジタルスイッチの釦兼回転摘みであるが、演算処理装置(62)をCPUとする場合には、キーボードとすることができ、その場合には、無論、重量を含む各種データを(演算の結果及び/又は入力手段からの入力信号の結果に基いて)書替可能に格納(即ち逐次CPUに呼出され、演算され、演算結果を再度逐次格納)するRAM、及び、該各種データを演算処理するための処理プログラムと各種指令情報発信プログラムとを含む各種プログラムを呼出自在に格納するROMを付すことができ、そして、演算処理装置(62)は、前記演算結果に基いて、例えば前記第1〜3の送気調節弁(33b)、(21b)、(15b)の開閉指令信号を送信するようなプログラムを有するものに構成することができる。   The input means (64) in this example is a button / rotary knob of a digital switch as a code generator (binary code), but if the arithmetic processing unit (62) is a CPU, it can be a keyboard. In that case, of course, various data including the weight are stored so as to be rewritable (based on the result of the operation and / or the result of the input signal from the input means) (that is, sequentially called by the CPU, calculated, and calculated) RAM for storing results again sequentially), and ROM for storing various programs including a processing program for arithmetic processing of the various data and various command information transmission programs can be attached, and arithmetic processing The device (62) transmits, for example, the opening / closing command signals of the first to third air supply control valves (33b), (21b), (15b) based on the calculation result. It can be configured to have a such a program.

本発明の充填装置においては、大型容器の排出口側の微粉体堆積量が増えると、その分空気の抵抗が大きくなり、連結管内の微粉体の移送速度が小さくなり、移送が自動的に停止することがある。微粉体の流動化はこれを防ぐが、大型容器内への送気による微粉体層の膨張の程度(微粉体雲の大きさ程度)は、微粉体層の深さの(20%〜500%)程度に調整すべきであり、これより少ないと円滑な排出ができにくく、多いと容器内で粉体の局部的渦流や、吹き上げが起きて好ましくない。計量槽内の微粉体層の膨張の程度(トナー雲の大きさ程度)は、微粉体層の深さの(25%〜600%)程度に調整することが好ましい。また、流動化したトナー層のかさ密度を高める手段として、多孔質板のエアスライダを分割して間欠的に供給空気を送り、粉体を分割したパルス状にして輸送することもできる。   In the filling apparatus of the present invention, when the amount of fine powder deposited on the discharge port side of the large container increases, the resistance of air increases accordingly, the transfer speed of the fine powder in the connecting pipe decreases, and the transfer automatically stops. There are things to do. Although the fluidization of the fine powder prevents this, the degree of expansion of the fine powder layer (the size of the fine powder cloud) due to the supply of air into the large container is 20% to 500% of the depth of the fine powder layer. If the amount is less than this, smooth discharge is difficult, and if the amount is too large, local vortex flow or blow-up of powder occurs in the container, which is not preferable. The degree of expansion of the fine powder layer in the measuring tank (the magnitude of the toner cloud) is preferably adjusted to about (25% to 600%) of the depth of the fine powder layer. Further, as means for increasing the bulk density of the fluidized toner layer, the air slider of the porous plate can be divided and the supply air can be intermittently sent to transport the powder in the form of divided pulses.

図1に示される微粉体充填装置を用いた微粉体充填方法の例を説明すると、この微粉体充填装置は、トナーの充填装置として、トナー製造工場内、保管及び出荷部門、オフィス内での例えば複写機近傍で使用することができるが、例えば複写機近傍で使用する場合には、キャスタ付台車上に気体供給源としての圧力容器と共に設けることが望ましく、また圧力容器に圧縮空気を蓄えるためのコンプレッサを付属させることができる。   An example of a fine powder filling method using the fine powder filling apparatus shown in FIG. 1 will be described. This fine powder filling apparatus is used as a toner filling apparatus in a toner manufacturing factory, storage and shipping department, office, for example. Although it can be used in the vicinity of a copying machine, for example, when used in the vicinity of a copying machine, it is desirable to provide a pressure vessel as a gas supply source on a caster-equipped carriage, and for storing compressed air in the pressure vessel. A compressor can be attached.

本発明の微粉体充填装置は、広く微粉体を小型トナー容器に充填する用途に使用することができるが、具体的にはトナー、薬品、化粧品、食品等の粉体を粉体容器内に充填するために用いることができ、特にトナーを小型トナー容器に充填するために好適に用いることができる。   The fine powder filling device of the present invention can be widely used for filling fine powder into a small toner container. Specifically, powders such as toner, chemicals, cosmetics, and foods are filled in the powder container. In particular, it can be suitably used to fill a small toner container with toner.

以下、本発明の微粉体充填方法の実施例について説明する。トナー充填装置の一例を次に示す。この装置における大型容器(10)の容量は25〜500lであり、大型容器(10)へのトナー収納量は一般的に10〜200kgである。大型容器(10)底部の傾斜角度は好ましくは30〜60°であり、連結管(20)取りつけ傾斜角度は30〜60°であることが好ましい。連結管(20)の途中には、図2に示すように、連結管(20)の途中にフランジ(2a)(2b)を設け、フランジ(2a)とフランジ(2b)の間に、目開き2.00mmのステンレス製の網目状フィルタ(1)をパッキン(3a)(3b)で挟んで挿入し、フランジ(2a)とフランジ(2b)をねじで固定した。
尚、この装置の仕様は、網目状フィルタ(1)を設けた以外は、特許文献2の実施例で用いた装置と同様である。
Examples of the fine powder filling method of the present invention will be described below. An example of the toner filling device is shown below. The capacity of the large container (10) in this apparatus is 25 to 500 l, and the amount of toner stored in the large container (10) is generally 10 to 200 kg. The inclination angle of the bottom of the large container (10) is preferably 30 to 60 °, and the connection tube (20) mounting inclination angle is preferably 30 to 60 °. In the middle of the connecting pipe (20), as shown in FIG. 2, a flange (2a) (2b) is provided in the middle of the connecting pipe (20), and an opening is provided between the flange (2a) and the flange (2b). A 2.00 mm stainless steel mesh filter (1) was inserted between the packings (3a) and (3b), and the flange (2a) and the flange (2b) were fixed with screws.
The specification of this apparatus is the same as that of the apparatus used in the example of Patent Document 2, except that the mesh filter (1) is provided.

この例における計量槽(30)の容量は0.5〜20lであり、計量槽(30)内のトナー量は一般的に50〜2000gであることが好ましい。この例の装置は、2成分非磁性トナー(カラートナー、モノクロトナー)、1成分非磁性トナー(カラートナー、モノクロトナー)、1成分磁性トナー(モノクロトナー)、フェライト系キャリア現像剤、マグネタイト系キャリア現像剤等に適用できる。   The capacity of the measuring tank (30) in this example is 0.5 to 20 l, and the amount of toner in the measuring tank (30) is generally preferably 50 to 2000 g. The apparatus of this example includes a two-component non-magnetic toner (color toner, monochrome toner), a one-component non-magnetic toner (color toner, monochrome toner), a one-component magnetic toner (monochrome toner), a ferrite carrier developer, and a magnetite carrier. Applicable to developers and the like.

この例の装置におけるトナー流動化開始と安定化例について説明すると、3〜5kg/cmの流動化エアー圧、0.1〜1l/分の流動化エアー流量で運転することができるが、流動化安定化までに要する時間は一般的に5〜20秒である。先に説明したように、トナーを流動化させるためにエアーを流し、計量槽(30)内で更にエアー含有量(固体と気体の比率)を安定化(一定化)させる。 An example of toner fluidization start and stabilization in the apparatus of this example will be described. It can be operated with a fluidizing air pressure of 3 to 5 kg / cm 2 and a fluidizing air flow rate of 0.1 to 1 l / min. The time required for stabilization is generally 5 to 20 seconds. As described above, air is flowed to fluidize the toner, and the air content (ratio of solid to gas) is further stabilized (stabilized) in the measuring tank (30).

次に、トナーの充填開始について説明すると、この例の装置における吐出制御部材(32d)の外径は5〜50mmであることが好ましく、弾性体リング(32a)の内径は5〜50mmであることが好ましい。吐出制御部材(32d)の外径と弾性体リング(32a)の内径の差は一般的に−0.5〜+2.0mmである。吐出制御部材(32d)を上昇させることによって、弾性体リング(32a)との隙間を大きく空けてトナーを落下させ、小型容器(40)への充填を開始する。   Next, the start of toner filling will be described. The outer diameter of the discharge control member (32d) in the apparatus of this example is preferably 5 to 50 mm, and the inner diameter of the elastic ring (32a) is 5 to 50 mm. Is preferred. The difference between the outer diameter of the discharge control member (32d) and the inner diameter of the elastic ring (32a) is generally -0.5 to +2.0 mm. By raising the discharge control member (32d), the gap between the elastic ring (32a) and the elastic ring (32a) is increased to drop the toner, and the filling into the small container (40) is started.

トナーの停止は、次のように行なわれる。即ち、弾性体リング(32a)への吐出制御部材(32d)の挿入と吐出開口部(31)の開閉が行なわれるが、弾性体リング(32a)への吐出制御部材(32d)の挿入度合と吐出開口部(31)の開閉度は、第1段階で、挿入度合0〜10%−開閉度95〜100%、第2段階で挿入度合40〜60%−開閉度5〜30%、第3段階で挿入度合95〜100%−開閉度0〜5%が目安になる。第1段階で小型容器(40)への規定充填量の大部分を充填し、第2段階で規定重量になるまで精密充填を行なって、規定量に達したら第3段階にてトナーの流れを停止する。   The toner is stopped as follows. That is, the discharge control member (32d) is inserted into the elastic ring (32a) and the discharge opening (31) is opened and closed, and the degree of insertion of the discharge control member (32d) into the elastic ring (32a) is determined. In the first stage, the opening degree of the discharge opening (31) is 0 to 10% insertion degree—95 to 100% opening degree, and 40 to 60% insertion degree in the second stage—5 to 30% opening degree. The degree of insertion is 95 to 100% and the degree of opening and closing is 0 to 5%. In the first stage, most of the prescribed filling amount into the small container (40) is filled, and in the second stage, the filling is performed precisely until the prescribed weight is reached. Stop.

上記のように網目状フィルタ(1)を設けた場合と、フィルタを設けない場合の充填制御不良現象の発生、吐出開閉部(31)付近のトナーをサンプリングして、微粉体やゴミの混入を調べた結果を表1に示す。表1に示すように、フィルタを設けた場合は、1000kgのトナーを充填した後であっても、充填制御不良現象が起きなかった。これに対し、フィルタを設けない場合は、200kgのトナーを充填すると、吐出開閉部に微粉体やゴミが溜まり、充填制御ができなくなった。     As described above, when the mesh filter (1) is provided and when the filter is not provided, the filling control failure phenomenon occurs, the toner near the discharge opening / closing part (31) is sampled, and fine powder and dust are mixed. The examination results are shown in Table 1. As shown in Table 1, in the case where the filter was provided, no poor filling control phenomenon occurred even after 1000 kg of toner was filled. On the other hand, in the case where no filter was provided, when 200 kg of toner was filled, fine powder and dust accumulated in the discharge opening / closing part, and filling control could not be performed.
